485 cheetah jetting

[kevincurtis]

Was wondering if i could get some information on what jetting to run with the 485 cheetah at sea level + dome size ( 91 octane  pump gas) would like to know what people are running to start with a good base , I have Keihn D-slide carbs.

What size carbs, domes, what pipes, porting?

 

For what it's worth, i have the same motor, I'm running 20cc domes, pipes are Vito's fat bastard, carbs are 35pwks. Port work from Wildcard racing.
